We are really hoping to snag a Palo brunch on board if nothing opens up in the coming weeks. I have read that sign-ups usually open in one of the MDR's around 12:30/1 on embarkation day. My question is, if we board at 11:30/11:45, should my husband head straight there to wait until it opens to have a chance? Or does the line not form until closer to the sign-ups opening? Some people said that they were able to grab a reservation as soon as they got on board so I was just confused if they sometimes open earlier than the time listed on the navigator or maybe those people just boarded closer to 12:30/1. We will be on the Fantasy if that makes a difference.Thank you!
